ことができる。 The present invention will be explained in detail based on examples in FIGS. 3 and 4. A switch contact (not shown) is provided inside the switch case 1, and the lower end of the handle 3 protrudes into the switch case 1 when the handle 3 held by the mounting tube 2 attached to the top surface swings. to open and close the switch contacts. The mounting tube 2 is formed into a cylindrical shape with both upper and lower ends open, and is fixed to the upper surface of the switch case 1 by caulking the leg pieces 15 protruding from the lower end to the upper wall of the switch case 1. A flange 16 that forms a circumferential groove 17 on its upper surface extends from the outer periphery of the lower end of the mounting tube 2, and a panel mounting O-ring 18 and the mounting tube 2 are fitted into the circumferential groove 17 when the switch case 1 is attached to the panel 20. The panel 20 is sandwiched between the O-ring 18 and a nut 19 screwed onto the upper end of the O-ring 18, and the O-ring 18 is pressed against the panel 20, thereby waterproofing the attachment point to the panel 20. A groove 5 is formed on the inner periphery of the upper end of the mounting tube 2, and an O-ring 6 accommodated in the groove 5 provides waterproofing between the handle 3 and the attachment tube 2. The handle 3 has a spherical shaft part 4 formed in the middle part in the longitudinal direction.
is fitted into the mounting tube 2 so that the operating section at the upper end projects upwardly from the mounting tube 2, and the switch contact opening/closing section 10 at the lower end projects into the switch case 1,
The spherical portion of the spherical shaft portion 4 is brought into sliding contact with the inner circumferential surface of the mounting tube 2, so that the spherical shaft portion 4 can freely swing around the spherical center thereof. On the other hand, a pair of support pieces 14 protrudes from the upper surface of the switch case 1 to sandwich the switch contact opening/closing part 10 at the lower end of the handle 3 from both sides.
The operating direction is defined, and the handle 3 is supported by both support pieces 14.
It is possible to swing freely in the direction perpendicular to the line connecting the . Each support piece 14 comes into contact with the upper bottom surface of the notched step part 13 formed on both sides of the lower end of the ball shaft part 4 at its upper end, pushes the ball shaft part 4 upward, and seals the top surface of the ball shaft part 4 with the O-ring 6 in a water-tight manner. Attach the ball shaft part 4 to the mounting tube 2 in a state where they are in close contact with each other.
hold it in place within the The upper end of each support piece 14 is finished with a convex curved surface and formed in a substantially arc shape, so that the support piece 14 is always connected to the notch step 1 while the handle 3 is swinging.
By maintaining point contact with the handle 3 and minimizing the frictional force between the two, the handle 3 can be operated with light force.

Since the present invention has the above-mentioned configuration, in addition to waterproofing the handle mounting part by bringing the spherical shaft of the handle into close contact with the O-ring, it also regulates the swinging direction of the handle to prevent horizontal swing of the handle. This can be achieved with a pair of support pieces installed on the switch case, and the waterproofing and rolling prevention can be done with one type of member.The advantage is that the number of parts can be reduced and assembly can be simplified. Yes, also
Since the arcuate portion formed at the upper end of each support piece contacts and supports the spherical shaft of the handle through point contact, the friction between the support piece and the spherical shaft when the handle swings is reduced. The force can be reduced and the handle can be operated with a slight force, and one point on the top of the support piece is always in point contact with the notch step, so when operating the handle by tilting it to the left or right, the support that supports the handle can be used. Since the pieces are supported by point contact, the support state will not change when the handle swings, preventing the handle from being pushed upwards and causing damage due to deformation force being applied to other parts. The advantage is that you can avoid doing this. In addition, since the support piece supports the upper bottom surface of the notch step, the support piece supports the ball shaft part in the vertical direction, and the force applied to the support piece is a vertical force. Since the support piece supports the ball shaft in the vertical direction, the support piece is unlikely to be deformed or worn out even after long-term use. The shaft part is supported reliably, and the ball shaft part can be pushed upward to ensure pressure contact with the O-ring, ensuring waterproofness over a long period of time, and is highly reliable.
